From Fig. 3 it may F1 1 1 f 1 also be understood in that the frame sections i 1011? Y m 13 are shown in the fully opened position.

An arrangement is provided to limit opening of the frame sections 13 to 180. This arrangement comprises arranging the hinges 14 so that edges 20 of the projections 19 engage against each other when in the 180 position. This may be understood by examining Fig. 2 which is a side elevational view. The projections 19 are integral with the material of the frame sections 13. The hinges 14 are arranged upon the inner faces of the projections 19 and the leaves of the hinges may be secured upon the projections by rivets, solder or any other arrangement.

The attachment of the frame sections 13 upon the material of the opening 12 of the bag 10 comprises engaging the edges of the opening, see Fig. 4, between the frame sections 13 and holding strips 21. These holding strips are also of inverted U-shape so as to extend over and along the frame sections. Rivets, bolts or any other means may serve to hold the strips 21 together with the frame sections 13 in an integral unit. Soft material 22 such as felt strips also of inverted U-shape are attached upon the outer faces of the strips 21 and serve to produce a dust tight joint when the frame sections are in the closed position. These felt strips 22 may be attached by cement, glue or the like. The openings 18 and the lugs 17 may be used for supporting the vacuum cleaner bag upon the customary handle or pole of a vacuum cleaner.

The frame section 13 may be of any desired shape. For example, frame section 13 is illustrated with angular contours instead of the round frame section 13.

In Figs. 6-8 inclusive a modification of the invention has been disclosed wherein extensions are provided for the projections 19 to facilitate stepping upon the projections and extension to hold the bag in its emptying position. More particularly an extension 23 is provided for each of the projections 19. Each extension 23 is pivotally mounted by reason of a rivet 24 which engages through the projection 19 and the particular extension. Each of the extensions 23 is provided with an elongated slot 25 through which the rivet 24 engages so that the extension may be slightly raised when desired. Axial springs 26 are arranged upon the rivets 24 and act between the projections 19 and the extensions 23 to normally pivot the extensions into open positions indicated by the dot and dash lines in Fig. 6. Lugs 27 project from the ends of the projections 19 and extend into the path of motion of the extensions 23 to limit their pivoting through ninety degrees, so that it is to be in line with the longitudinal lengths of the projections 19.

Hooks 28 project from the sides of each of the extensions 23 and are adapted to engage into the openings 30 formed in the ends of the channel shaped clamp member 15. The arrangement is such that the extension in the raised positions serve as latches for holding the channel shaped clamp 15 in position. The clamp 15 may be released by manually lifting the extensions 23 as permitted by the slots 25 so that springs 26 may pivot the extensions into the extended positions. Then the channel shaped clamp 15 can be removed from the frame sections and the frame sections pivoting open to 180. Because of the extensions 23 it is convenient for a person to stand with one foot upon each side of the frame section so that each of the feet engage an adjacent pair of the projections 19 and the extensions 23 for the purpose of simultaneously holding the frame down so that the bag may be emptied and furthermore preventing the closing of the frame sections during the emptying of the bag.

While I have shown and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:-

3. A dust eliminator vacuum cleaner bag emptying device, comprising a vacuum cleaner bag having an inlet at one end and a large opening at the other end, a frame upon the material of said bag around the edge of said opening and comprising a pair of inverted U-shaped frame sections hingedly connected at their ends, means for holding said frame sections closed, projections from the ends of said frame sections to be stepped upon for holding the frame sections open and down during emptying, and extensions hingedly mounted upon said projections, means urging said extensions outwards, hooks upon the edges of said extensions adapted to engage into openings formed in the ends of a clamp engaged upon said frame sections and constituting said means for holding the frame sections closed.

4. A dust eliminator vacuum cleaner bag emptying device, comprising a vacuum cleaner bag having an inlet at one end and a large opening at the other end, a frame upon the material of said bag around the edge of said opening and comprising a pair of inverted U-shaped frame sections hingedly connected at their ends, means for holding said frame sections closed, projections from the ends of said frame sections to be stepped upon for holding the frame sections open and down during emptying, and extensions hingedly mounted upon said projections, means urging said extensions outwards, hooks upon the upper edges of said extensions adapted to engage into openings formed in the ends of a clamp engaged upon said frame sections and constituting said means for holding the frame sections closed, said extensions being formed with slots at the pivot to allow slight longitudinal motion.

5. A dust eliminator vacuum cleaner bag emptying device, comprising a vacuum cleaner bag having an inlet at one end and a large opening at the other end, a frame upon the material of said bag around the edge of said opening and comprising a pair of inverted U-shaped frame sections hingedly connected at their ends, means for holding said frame sections closed, projections from the ends of said frame sections to be stepped upon for holding the frame sections open anddown during the emptying, and extensions hingedly mounted upon said projections, means urging said extensions outwards, hooks upon the edges of said extensions adapted to engage into openings formed in the ends of a clamp engaged upon said frame sections and constituting said means for holding the frame sections closed, said extensions being formed with slots at the pivot to allow slight longitudinal motion, and stop lugs projecting from said projections to limit motion of the extensions to be in line with the projections. 1
